Michigan high school shooting suspect, 15, appears at court hearing

Ethan Crumbley's parens had been summoned to school over behavioral concerns hours before attack, authorities say

The 15-year-old boy charged with murder and terrorism for a shooting that killed four fellow students and injured others at a Michigan high school was seen in custody via video during a court hearing on Wednesday afternoon.

He appeared as county authorities revealed that his parents had been summoned to the school hours before the attack - and the county prosecutor spoke out about gun control after it was revealed that the handgun used in the shooting at Oxford high school, about 30 miles north of Detroit, belonged to the suspect's father.
